CONDENSER P11313.

Application led May 13.

This invention relates to condenser pipes and more particularly tocondenser vpipesA of the Vtype employing internal corrugations forbreaking up the vapor stream within the pipe to prevent passage throughthe pipe of a core of uncondensed vapor which has not come in Contactwith the walls ofthe pipe.

An important object of the invention is to produce a device of thischaracter having a plurality of drainage pairs wherein the inner wallsof the pipe is straight, preventing pocketing of the'condensed liuids,these drainage pairs corresponding in number and arrangement to thefacets of the pipe flange so that any particular facet may be upwardlydisposed and still a proper drainage path provided.

A further object of the invention is to produce a device of thischaracter which may be readily manufactured and in which a maximumradiation surface is provided.

These and. other objects I attain by the construction shown in theaccompanying drawings,wherein for the purpose of illustration is shown apreferred embodiment of my invention and Whereinz Figure l is an endelevation of a condenser pipe constructed in accordance with myinvention;

Figure 2 is a fragmentary side elevation thereof; .f

Figure 3 is a section on the line 3 3 of Figure 1;

Figure 4 is a section on the line 4.--4 of Figure 2;

Figure is a section on the line 5--5 of Figure 4.

Referring now more particularly to the drawings, the pipe consists ofalternate polygonal and round sections 10 and 11, the sections 10 beingin the present illustration disclosed as rectangular. These sections maybe made with any suitable number of sides, but the number of sidesemployed should correspond with the number of sides upon the couplingiange 12 provided at the end of the pipe. 'Ihe internal diameter of theround sections 11 is the same as the inscribed diameter of the polygonalsections 10 so that a section taken along sections of the correspondingsides of the polygonal sections will provide a straight Hat wall 13 uponthe interior of the pipe along which fluids may travel. It will, ofcourse, be understood that a polygonal section having an even number ofsides must be employed,

so that when'an upper facet 14 the flange aries. i

is horizontally arranged'a diametrically op-k posed lower facet l5islikewise horizontally arranged.

The interior angles 16 between ad]acent sides of the rectangular sectionare rounded,

as'illustrated, so that no pocket is formed in which condensed fluidswill tend to' `collect and so that all of these Vcondensed fluids willbe directed toward the path provided at thel bottom of the pipe fortheir passage. The i perimeter of each rectangular rsection is formedwith a projecting rib or vane 17 to increase the coolingsurface'provided. It will rbe noted that in alignment with thecorresponding included angles of the polygonal sections a vsinuous wall18 is produced which will tend to keep the passing vapors in continuousmotion to break up the core of the vapor stream. There will be walls 18corresponding in number to theincluded angles y16 of each polygonalsection and their combined action upon the vapor stream will tend tovery thoroughly break the .stream up, bringing all parts of the vaporinto contact with the walls ofthe pipe.

It will7 of course, be understood that in referring to rectangular andround sections,

reference is had to the construction of theY 1. A condenser pipe formedinteriorly to produce alternate round and polygonal sections. thepolygonal sections having corresponding sides thereof disposed in commonplanes tangential to the round sections whereby the round and polygonalsections combine to produce wall sections correspond-A ing in number tothe sides of the polygonal sections in which the points of tangency andthe mid-points of thecorresponding sides of the polygonal sections linein the sam straight lines.

A condenser pipe formed interiorly to produce alternate round andpolygonal sections, the polygonal sections having corresponding sidesthereof disposed in common planes tangential to the round Sectionswherebyv the round and vpolygonal Section combine to produce wallsections corresponding in nuniber to the sides olf the polygonalsections in which the points of tangenoy and the .mid-points of thecorresponding sides of the polygonal sections lie in the saine Straightlinee`r the exterior of the pipe being provided in alignment With eachpolygonal seotion with an outstanding cooling rib.
